Relationship between physical fitness, body composition indicators and physical activity components in Spanish schoolchildren
Esta Tesis Doctoral se basa en un proyecto de investigación longitudinal del grupo E-FIT (Ejercicio físico, salud y calidad de vida) denominado 'Observatorio de Actividad Física en población escolar https://observatorio ... -
Resilience assessment of lowland plantations using an ecosystem modeling approach
As afforestation programs of former farmlands take hold in Taiwan to achieve a variety of ecological and socio-economic values, it is becoming necessary to define best forest management. Hence, we simulated mixed ... -
Seed origin and protection are important factors affecting post-fire initial recruitment in pine forest areas
Initial seedling recruitment is one of the most critical stages for plants in the Mediterranean basin. Moreover, wildfires and post-fire environmental conditions might deteriorate regeneration success, which can lead to ... -
Shelf life of ground beef enriched with omega-3 and/or conjugated linoleic acid and use of grape seed extract to inhibit lipid oxidation
The shelf life and oxidative stability of refrigerated raw ground beef enriched with omega-3 and/or conjugated linoleic acid (CLA) were studied. Grape seed extract (GSE) was used to inhibit lipid oxidation in the ground ... -
Significant increase in ecosystem C can be achieved with sustainable forest management in subtropical plantation forests
Subtropical planted forests are rapidly expanding. They are traditionally managed for intensive, short-term goals that often lead to long-term yield decline and reduced carbon sequestration capacity. Here we show how it ... -
Simulando la interacción entre la densidad inicial y los flujos de agua y nutrientes para comprender el desarrollo de rodales mixtos de Pinus sylvestris y Fagus sylvatica bajo cambio climático
La gestión de bosques mixtos se ha convertido en una estrategia de adaptación para reducir los riesgos relacionados con el cambio climático. A su vez, los modelos ecológicos pueden ser una herramienta útil para el estudio ... -
La sobreexpresión del gen ALDH7B4 alivia los efectos provocados por herbicidas inhibidores de la biosíntesis de aminoácidos
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEn este trabajo se ha profundizado en el conocimiento de los efectos fisiológicos provocados por los herbicidas imazamox y glifosato. En concreto, se ha estudiado el papel de la ALDH7B4, aldehído deshidrogenasa, que ... -
Soil degradation and soil quality in Western Europe: current situation and future perspectives
The extent and causes of chemical, physical and biological degradation of soil, and of soil loss, vary greatly in different countries in Western Europe. The objective of this review paper is to examine these issues and ... -
Soil organic matter: a sustainability indicator for wildfire control and bioenergy production in the urban/forest interface.
Many rural communities in British Columbia (western Canada) are increasingly at risk from wildfire as temperatures rise and droughts become more frequent. In addition, these communities are also faced with rising fuel ... -
Soil quality and factors of organic matter stabilization in agricultural soils recently converted to irrigation in the Ebro Valley
El trabajo realizado en esta tesis ha permitido avanzar en el conocimiento de los mecanismos de estabilización de la materia orgánica en suelos agrícolas semiáridos mediterráneos, así como de los factores tanto edáficos ... -
Soil quality evaluation following the implementation of permanent cover crops in semi-arid vineyards. Organic matter, physical and biological soil properties
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2012) Artículo / ArtikuluaEl establecimiento de cubiertas vegetales permanentes (PGC) en viñedos de zonas semiáridas, con manejo tradicional de suelo desnudo mediante laboreo y aplicación de herbicidas, es controvertido, porque tiene ventajas ... -
Soybean dihydrolipoamide dehydrogenase (ferric leghemoglobin reductase 2) interacts with and reduces ferric rice non-symbiotic hemoglobin 1
Ferrous oxygenated hemoglobins (Hb2+O2) autoxidize to ferric Hb3+, but Hb3+ is reduced to Hb2+ by enzymatic and non-enzymatic mechanisms. We characterized the interaction between the soybean ferric leghemoglobin reductase ... -
Split‐root systems applied to the study of the legume‐rhizobial symbiosis: what have we learned?
Split-root system (SRS) approaches allow the differential treatment of separate and independent root systems, while sharing a common aerial part. As such, SRS is a useful tool for the discrimination of systemic (shoot ... -
Survival and growth as measures of shade tolerance of planted western redcedar, western hemlock and amabilis fir seedlings in hemlock-fir forests of northern Vancouver Island
We examined two measures of shade tolerance (survival and growth) of planted 1-year-old seedlings of western redcedar (Thuja plicata (Donn ex D. Don)), western hemlock (Tsuga heterophylla ([Raf.] Sarg.)) and amabilis fir ... -
Sustainable management of metasequoia glyptostroboides plantation forests in Shanghai
Urban forestry is increasingly used as a tool for climate change mitigation and for providing environmental services to inhabitants of urban areas. However, tree species used in urban forestry are usually different from ... -
Temporal interactions among throughfall, type of canopy and thinning drive radial growth in an Iberian mixed pine-beech forest
Many factors can influence tree growth over time such as different forest management practices, climate or tree-to-tree interactions, especially in mixed forests. We show in this work how the temporal growth patterns ... -
Tillage effects on soil quality after three years of irrigation in Northern Spain
Irrigation is being initiated on large areas of traditionally rainfed land to meet increasing global demand for food, feed, fiber and fuel. However, the consequences of this transition on soil quality (SQ) have scarcely ... -
Tree-to-tree competition in mixed European beech-Scots pine forests has different impacts on growth and water-use efficiency depending on site condition.
Mixed conifer-hardwood forests can be more productive than pure forests and they are increasingly considered as ecosystems that could provide adaptation strategies in the face of global ... -
Unravelling the mechanisms that improve photosynthetic performance of N₂-fixing pea plants exposed to elevated [CO₂]
Although the predicted enhanced photosynthetic rates of plants exposed to elevated [CO₂] are expected to increase carbohydrate and plant growth, recent findings have shown a complex regulation of these processes. The aim ... -
